About Eikichi Yazawa
Eikichi Yazawa is a Japanese singer-songwriter. He is the father of singer Yoko Yazawa. He has been nicknamed as "Ei-chan" (永ちゃん), "Boss" and "The King of Rock". Thus, his first solo concert tour, E.Yazawa Around Japan Part-1, ended disastrously, as Yazawa could not fill the venue in Sasebo city, Nagasaki, which only held 1,500 people. After the remarkable success of his third album Open Your Heart, Yazawa played his first solo performance at Nippon Budokan on August 26, 1977, to a sold-out crowd of over 13,000 people.
